1994 Ford Bronco C101 In-Line Connector Pinout - 42-Pin Wire Colors & Circuits

This document is a connector pinout reference for the C101 in-line connector on a Ford Bronco (labeled "94 Bronco"), applicable to 4.9L, 5.0L, 5.8L, and 7.5L engines. It shows face views of both halves of the 42-cavity connector, C101F (female) and C101M (male), with each pin cavity numbered 1 through 42. Below each connector drawing is a table listing every pin number with its corresponding circuit number and wire color code, for example pin 1 = circuit 101 (GY/Y, gray/yellow), pin 9 = circuit 57 (BK, black ground), pin 22 = circuit 200 (BR), and pin 30 = circuit 570 (BK/W). Several cavities (8, 17, 28, 29, 40, 41, 42) are unpopulated, indicated by a dash. The two tables are essentially mirror images, allowing a technician to trace which circuit passes through each side of the connector. A reader can use this page to identify wires at the C101 bulkhead/in-line connector by pin position, circuit number, and insulation color when diagnosing wiring problems, testing continuity, or repairing damaged terminals on the engine or body harness of a mid-1990s Bronco.
